For the specific study design, such as randomized control studies, studies of diagnostic accuracy, meta-analyses, observational studies and non-randomized studies, it is recommended that the authors follow the reporting guidelines listed in the following table.

Drug and chemical names should be stated in standard chemical or generic nomenclature.

Description of genes or related structures in a manuscript should include the names and official symbols provided by the US National Center for Biotechnology Information (NCBI) or the HUGO Gene Nomenclature Committee.

Standard metric units are used for describing length, height, weight, and volume. The unit of temperature is given in degree Celsius (℃). Specifically, use ‘sec’, ‘min’, ‘hr’, ‘day’, ‘wk’, ‘mo’, and ‘yr’ for time units. All others units of measure should be presented according to the International System (SI) of Units. All units must be preceded by one space except percentage (%) and temperature (℃).

B. Original articles

Manuscripts will not be acceptable for publication unless they meet the following editorial requirements. Manuscripts include 1) Title page, 2) Structured abstract and Keywords, 3) Introduction, 4) Materials and Methods, 5) Results, 6) Discussion, 7) Acknowledgements, 8) References, 9) Tables, and 10) Figure legends. Each component should begin on a new page in the following sequence. Manuscripts should be no longer than 5,000 words and the combined numbers of tables and figures should be no more than 10 items.

1) Title page

Provide running title (a maximum of 40 spaces and letters), manuscript title, author’s full name and institution. For different institution, use the sequential Arabic number (1, 2, 3…) in superscript ahead of institution.

All persons designated as authors should be qualified for authorship (See the part of ETHICS IN PUBLISHING). Each author should have participated sufficiently in the work to take public responsibility for the content.

Include any financial support (grant number, institution and location) or presentation history at a meeting.

2) Structured abstract and Keywords : The abstract should present the Objective, Methods, Results, and Conclusion. The abstract should also emphasize new and important aspects of the study or observation and tract may not exceed 250 words. Below the abstract, provide up to 10 keywords that will assist indexers in cross-indexing the article. For selecting key words, refer to the Index Medicus Medical Subject Headings.

4) Methods : Describe the research plan, the materials (or subjects), and the methods used, in that order. Explain in detail how the disease was confirmed and how subjectivity in observations was controlled. When experimental methodology is the main issue of the paper, describe the process in detail so as to recreate the experiment as closely as possible. The sources of the apparatus or reagents used should be given along with the source location (name of company, city, and country). If needed, include information on the IRB/IACUC approval and informed consent. Methods of statistical analysis and criteria for statistical significance should be described.

5) Results : The results should be presented in logical sequence in the text, tables, and illustrations. Do not repeat in the text all data in the tables or figures, but describe important points and trends.

6) Discussion : Observations pertaining to the results of research and other related materials should be interpreted for your readers. Emphasize new and important observations; do not merely repeat the contents in the Introduction or Results. Explain the meaning of the observed opinion along with its limits, and within the limits of the research results connect the conclusion to the purpose of the research.

7) Acknowledgments : Persons who have contributed intellectually to the paper but whose contributions do not justify authorship may be named and their function or contribution described, e.g., "scientific adviser," "data collections," or "participation in clinical trial." Such persons must have given their permission to be named. Authors are responsible for obtaining written permission from the persons acknowledged by name, because readers may infer their endorsement of the data and conclusions.

8) References : Number references consecutively in the order in which they are first mentioned in the text. References are identified by Arabic numerals in square bracket [ ]. Unpublished observations, and personal communications should not be used as references, although references to written, not oral communications may be inserted (in parentheses) in the text. Abstracts published in a citable journal may be cited. To cite a paper accepted but not yet published, state the paper's DOI number. References must be verified by the author(s) against the original documents. The titles of journals should be abbreviated according to the style used in Index Medicus (United States National Library of Medicine). List all authors in an article, but if the number exceeds six, give six followed by et al. Other types of references not described below should follow Citing Medicine: The NLM Style Guide for Authors, Editors, and Publishers.

9) Tables
Should be typed double-spaced on separate pages within manuscript, and they should be titled and numbered in Arabic numerals (not Roman numerals) in the order of their first citation in the text. Give each column a short heading. Place explanatory matter in footnotes, not in the heading. For footnotes use the following symbols, in this sequence: a, b, c, d, e, f in superscript. Do not use internal vertical lines.

10) Figures
Each figure should be submitted in a separate file, at a resolution of 600 dpi for photos and 1,200 dpi for line art. Lettering and identifying marks should be clear, and type size should be consistent on each figure. Capital letters should be used for specific areas of identification in a figure. Symbols, lettering, and numbering should be distinctly recognizable so that when the figure is reduced for publication each item will still be legible. Titles and detailed explanations belong in the figure legends, not on the illustrations themselves. Do not include figure legends in the same file as the figure, but place them instead on a page at the end of your manuscript.

D. Review paper
Review paper will be requested by the editors. Review articles are generally prepared in the same format as original articles, but the details of manuscript format may be flexible according to the contents. The manuscripts are limited to 5,000 words of text and includes 250-word summary in the place of unstructured abstract.

E. Brief communications
Brief communications submissions should be limited to 2,000 words of text and a maximum of one figure or one table. Include a 2-sentence narrative abstract in place of a structured abstract and do not include section headings.

F. Letters to the editor
This section of the journal is set aside for critical comments directed to a specific article that has recently been published in the journal. Letters should be brief (500 words), double-spaced, and limited to a maximum of 5 citations. The letters and replies should be prepared according to journal format. These will only be published in the on-line (blog) version of the journal for 6 months and then stored in the archives which are accessible to readers on-line. Illustrative material is accepted only with permission of the Editor. Please include your complete mailing address, telephone and fax numbers, and e-mail address with your correspondence.
The Editor reserves the right to shorten letters, delete objectionable comments, and make other changes to comply with the style of the journal.

A. Conditions of authorship
The CERM follows the recommendations for authorship by the International
Committee of Medical Journal Editors (ICMJE, 2010, http://www.icmje.org). Authors should have made significant conceptual, intellectual, experimental, and analytical contributions to the research, as well as having participated in writing and revising the manuscript. Each author should have participated sufficiently in the work to take public responsibility for its content. The Uniform Requirements by the ICMJE recommends authorship as follows.
Authorship credit should be based on 1) substantial contributions to conception and design, acquisition of data, or analysis and interpretation of data; 2) drafting the article or revising it critically for important intellectual content; and 3) final approval of the version to be published. Authors should meet these 3 conditions.

1) Falsification: Changing research materials, equipment or processes; omission of data or results. As a consequence, the research is not accurately represented in the research records. 2) Fabrication: Data, results or recording or reporting information that does not exist.3) Plagiarism: Using another person's words, ideas, results, and processes without giving credit to them constitutes plagiarism. Self-plagiarism can include multiple publications of essentially the same manuscript or data in different journals, books, or other publications. Plagiarism includes the theft of intellectual property, ideas or methods such as the use of information gained by personal communication or during a grant or manuscript review. Plagiarism also includes the direct textual copying of your own or another person's work. Direct copying of 250 words or more constitutes plagiarism. Differences of opinion or honest errors do not constitute misconduct.4) Duplicate publication: All papers that are submitted must report unpublished work and cannot be under consideration for publication elsewhere. If a manuscript contains more than 200 words of previously published text or if previously published figures or tables are submitted, written permission must be obtained from the holder of the copyright. Copies of permission letters must be submitted with the original manuscript. Material that is published without permission from the copyright holder will be considered duplicate publication, which is a serious offense. Previously published material can be cited in a manuscript, but it must be indicated by quotation marks. If more than 200 words from a previously published manuscript appear in a manuscript that is submitted as an original work and if this material is not indicated with quotation marks, the material will be considered to be plagiarized.5) Salami publications: Dividing data, analysis, and presentation into "minimally publishable units" is a slippery slope, and can be used to extend one data set over several manuscripts. While this may be acceptable for clarity of presentation and focus on specific outcomes in different manuscripts, a motivation may also be to increase the publication list in an author's CV. The latter is unethical and unacceptable.
